Ingredients

  • 2 tablespoons butter, plus more for greasing pan
  • 3/4 cup light brown sugar
  • 1 cup chopped pecans
  • 1 honeycrisp or Fuji apple, peeled, cored and diced
  • 1 lemon, zested
  • 3 teaspoons ground cinnamon
  • 1/8 teaspoon freshly ground nutmeg (8 scrapes on a fine grater)
  • 1/8 teaspoon ground cardamom
  • Generous pinch of salt
  • Pinch of salt
  • Flour, for dusting
  • 2 puff pastry sheets, thawed
  • 1 1/2 tablespoons butter, melted
  • 1/4 teaspoon vanilla extract
  • 1 1/2 tablespoons fresh lemon juice
  • 3/4 to 1 cup powdered sugar
  • Pinch of salt

Method

  • Special equipment: 10-inch round cake pan
  • Preheat the oven to 375 degrees F. Grease the sides and bottom of a 10-inch round cake pan with butter.
  • For the filling: In a bowl, add the brown sugar, pecans, diced apple, lemon zest, cinnamon, nutmeg, cardamom and a pinch of salt.
  • Stir until combined.
  • In a small pot, melt the 2 tablespoons butter with a pinch of salt.
  • Lightly dust a clean work surface with flour.
  • Flatten the puff pastry and roll with a rolling pin to even out and seal the perforations, if any.
  • Brush the butter all over the puff pastry, leaving a 1-inch border at one of the shorter ends.
  • Sprinkle the apple-cinnamon mixture evenly over the pastry sheet, being careful to leave that 1-inch border.
  • Starting from the end furthest from the edge without any filling, begin to tightly roll the pastry.
  • Tuck and press as you go, keeping the log as even as possible.
  • When the edge is reached, roll the pastry onto itself and press firmly, even pinching, to seal.
  • Using a serrated knife, trim the edges and gently cut 6 equal slices from each log.
  • Repeat with the second puff pastry sheet to make 12 pieces total.
  • Place the slices spiral side up in the prepared cake pan.
  • Start around the edges and fill in the center.
  • Bake until the pastry is cooked through and golden brown, 35 to 40 minutes.
  • Meanwhile, for the glaze: In a small pot, add the butter and melt over low heat.
  • Add the vanilla extract and lemon juice and begin whisking in the powdered sugar in 1/4 cup increments.
  • Continue adding and whisking between additions until the glaze thickens.
  • Season with a pinch of salt, then remove from the heat.
  • Remove the buns from the oven and pour the glaze over the top.
  • Let rest about 5 minutes before serving.
  • Serve warm.
